API standard 650 anchored tanks upper shell

In the petrochemical industry and other industries, large vertical API standard 650 anchored tanks are often used to store various production raw materials. Usually, the medium with high melting point and easy to crystallize at room temperature can be exported and used after heating, which involves the heating of large vertical storage tanks. The heating system is an auxiliary facility for heating of large vertical storage tank. It is often necessary to design external heating coil or internal heating coil system.

Normal pressure API 650 storage tank: When the gas side pressure of API 650 storage tank is the same as atmospheric pressure or less than 13 atmospheres (gauge), API standard 650 anchored tanks is called atmospheric storage tank. API 650 petroleum storage tanks low pressure storage tank: when the pressure is greater than 13 atmospheres (gauge) and less than 0.1MPa, it is called low pressure storage tank.

The main competitive means adopted by major domestic ports are to expand ports, build deep-water berths and channels, improve service quality to reduce the comprehensive cost of customers, and at the same time, to improve competitive advantage, we should also take appropriate measures to reduce relevant costs and prices.
